inner join problem

I have two tables:
* JobInfo - gives information about each job
* Employees - lists employees and their information

In each job, I need to create an entry that assigns a draftsman and a salesperson to each project (in the JobInfo table). I can't figure out how to join both the salesperson and the draftman fields to the employees table. Can somebody tell me what I'm doing wrong? Thanks in advance for the help.
